i will try and answer some of your questions.

3. no. wait to complete one year.

4. i suppose annual salary evaluation is common to all companies.

5&6. if your work will be in Ras Laffan, your housing will be in al-khor. whether your coming in as a bachelor or family status. it's a nice place, about 25 minutes from work. nothing to worry about.

7. possibly. but if you are simply an operator on an existing switch building or something along that line, then there could be a 4 hour overtime for you. It all depends on where you will be assigned. Will be a part of maintenance or not.

8. indefinite contract means a long contract. then that means your like part of a maintenance group. your in for a long haul.
